ENHANCED CONTINUUM GENERATION IN NONLINEAR BULK OPTIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To generate an enhanced (i.e., comparatively high power and/or wider band width) optical continuum from a bulk material.;SOLUTION: A bulk optic material is processed to form an element of a spatial microstructure such as a photonic bandgap structure. An ultra-short laser pulse is used as an input signal to be applied to bulk optic PBG structure to generate an enhanced continuum output. The PBG structure may comprise any type of one-, two- or three-dimensional structure, wherein the selected structure will dictate the types of enhancements that are present in the generated continuum generally in the form of a broadened continuum or the form of inclusion of one or more peaks in the continuum. The use of a relatively small-dimensioned bulk material allows the continuum to be generated without requiring any type of optical confinement (waveguide).;COPYRIGHT: (C)2008,JPO&INPIT
